BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to the field of data transfer to mobile phones/devices, and more particularly to delivering virtual books including content such as recreational, instructional, and informational content to data capable mobile phones/devices.

2. Related Art

Stories, whether delivered by a tribal raconteur or a working mom, have been handed down from generation to generation. Consider that one of the early forms of communications existed as petroglyphs on rocks or cave paintings on the walls of caves. Modem day storytelling can, of course, still be delivered by a human storyteller from memory or by reading a physical book. However, there are far more sophisticated and desirable options available today. Advanced communications in the form of radio and television broadcasts, videos (e.g., VHS and DVD), desktop/laptop computers, and intelligent purpose-built toys include those utilized on a daily basis.

Stories can be for enjoyment, education, or both. Today's devices can stimulate the brain by presenting material which requires understanding of content, new forms of speech, and problem solving. Use of these devices may also increase motor coordination, particularly in children. The devices that deliver this content are typically both everyday devices such as televisions, VCRs, and, computers, as well as purpose-built devices (e.g., small computers embedded in toys).

One device that has not been utilized for this type of content is a mobile phone/device. Mobile phones/devices are quickly becoming intelligent, robust devices. In the past few years, the world has seen the mobile phone advance from 13-button, no-display, bulky radio units to brilliant, color display, sleek, versatile computing devices. Some of these devices are starting to appear with standardized programmable operating systems (such as the Windows Operating System for desktop computers, for example). Such operating systems, when combined with robust hardware designs, now deliver applications capable of audio, video, robust user interaction, and robust internet web browsing. This platform when enabled with wireless data can become a powerful and capable delivery device.

In most civilized countries, the End Users of mobile phones/devices range from professionals to everyday consumers. Part of this demographic includes, for example, the parents of young children. Parents commonly carry these mobile phones/devices throughout the day to keep in touch with their family, friends, and work. These devices are often carried by the person when he or she leaves the home and are even close by when he or she is in the home.

There is a great need for providing content such as recreational, instructional, and informational content to devices such as mobile phones and their equivalents.

DETAILED DESCRIPTION OF THE INVENTION

The present invention in one embodiment provides a data capable mobile device, capable of receiving content and delivering it to a user. The present invention can take advantage of one or more of the device hardware, operating system, software, wireless data network, and the Internet in order to deliver specifically focused rich content to the device and End User(s). The content can include recreational, instructional, and informational content, and can include literature and games. The content can be aimed at children, parents, teachers, or all persons, of any age, interested in receiving entertainment or informational content, for example. This information can be retrieved in forms which include video data, audio data, text data, music, games, applications, and other types of software. The content itself can include, but is not in any way limited to, childrens' videos, childrens' music, childrens' learning applications/games, childrens' storybooks, childrens' cartoons, and other informational or educational content that uses a combination of video/audio and applications. The content can be tailored to others as well, for example by providing virtual novels for reading by the user. The phone/device can be combined with the content above and related ‘themes’ to ultimately form a device for parents, children, or people of all ages.

It is to be understood that the term “virtual book” as used herein includes content such as, for example, a novel, a book, a newspaper, a magazine, a pamphlet, a story, a training manual, a training guide, and others, which can be displayed page by page (if there is more than one page) on the mobile device, as if the user of the mobile device is reading a book. The virtual book can be displayed and accompanied by text, pictures, still video, moving video, animated pictures, and audio such as music, speech, etc.

In one embodiment of the invention the ‘home screen’ or display of the device has images related to the latest available content and links to both previously available and newly available content. This information can be automatically updated to the phone/device by a scheduled process on the device, or a ‘pushed’ message to the device. The choice can be left to the user. The phone/device can be configured to download the latest content, or wait for the user to request the content. The user can also receive ‘coming attractions’ displaying content which will be available in the future. The present invention can also deliver specifically tailored advertisements according to the user in response to the user's profile, or the user's selection of content. Such advertisements could include product advertisements, advertisements representing new content available for download, or others.

FIG. 1 illustrates a system for delivering content to a mobile phone/device in accordance with one embodiment of the present invention. Delivery of content is achieved via a wireless data connection that passes through a wireless data service provider. A host site 10 stores content which can be delivered to a mobile phone/device 16. The mobile phone/device 16 accesses the Internet 12 by way of a wireless network 14, and downloads content or a list of the content which is available for download. The host site 10 can be a website or websites, and can categorize the content according to type. Different types of content can include for example, content for children or teachers or adults; novels or instructional material; literature pertaining to sports or politics; fiction or nonfiction; or others. Content can be provided that is specifically tailored to the user(s). The content can be ‘streamed’ in real-time or completely downloaded to the device, for example. Once the content reaches the device, it can be displayed in various forms, thereby taking advantage of the robust features of the mobile device. Such forms include text, video, audio, photographs, etc., or some combination of these.

FIG. 2 illustrates a system for delivering content to a mobile phone/device in accordance with another embodiment of the present invention. In the embodiment shown in FIG. 2, delivery is achieved via a local pass-through connection to the user's computer which is connected to the public Internet. A host site 10 stores content to be delivered to a mobile phone/device 16. The mobile phone/device 16 accesses the Internet 12 by way of a cabled connection 18 to a computer 20 such as a desktop or laptop. In this setup, the computer 20 downloads the content or a list of the content which is available for download from the host site 10, and then delivers the content to the mobile device 16.

As in the embodiment shown in FIG. 1, the host site 10 can be a website or websites, and can categorize the content according to type, thereby providing content that can be specifically tailored to the user. The content can be ‘streamed’ in real-time or completely downloaded to the device for example. Once the content reaches the device, it can be displayed in various forms, thereby taking advantage of the robust features of the mobile device 16.

It is of course to be understood by those of skill in the art that various modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. For example, although a cabled connection is shown in FIG. 2, the connection could be wireless, such as a wireless data connection through a mobile operator. The mobile device 16 could be communicatively coupled to the computer 20 through any suitable type of communication link, using, for example, cable, telephone, or other wireless technologies.

In addition, instead of a host site 10 storing the content, content could be stored on a computer-readable medium such as a compact disc, and the compact disc could be read by the computer 20 for accessing the content. Media storing the content could be delivered to the user periodically. Alternatively, the mobile device 16 could sync up to a medium such as a removable memory to access the content.

FIG. 3 illustrates a process of requesting and delivering content from the host site 10 according to an embodiment of the present invention. Requests include manual requests and scheduled requests. Manual requests enable the user to choose data/content for delivery and then start the download of such content manually. Scheduled requests enable data/content to be automatically downloaded, for example via a predetermined schedule. The schedule can be programmed in advance by the user, or can be programmed by the mobile device 16 automatically based on user-implemented preferences or based on the user's profile.

In Step S1 of FIG. 3, a scheduled or manual request to download content is sent from the mobile device 16 to the host site 10. The process for sending a scheduled request can be achieved, for example, with a timer. For manual requests, the user can submit such requests through an exposed user interface. In Step S2 the host site 10 delivers the requested content, if it is available, to the mobile device 16 or to a computer 20 connected to the mobile device 16. In Step S3, the mobile device 16 transmits acknowledgments back to the host site 10 to confirm that delivery was completed and that the requested content was received. A log of this information is created as well. If an error occurred somewhere in the process, for example the delivery was incomplete, or the transmission was prematurely terminated, or the wrong content was received, etc., an error message is created and stored in the log, and this information is transmitted back to the host site. At this point the data can be re-transmitted in whole or part, or can be otherwise corrected.

If, for example, the requested content is not available, the host site 10 will update the error log and send a notification to the mobile device 16 or the computer 20. The user then has the option of requesting other content or terminating the process. The host site can also suggest content as a replacement, for example content that may be similar to the originally requested content.

The interface of the mobile device 16 is set up to allow the user to easily navigate through the available options. In one embodiment, the user uses the keys on the device 16 to select from a menu the options relating to the provision of content. The user is provided with options such as viewing a list of the content available for download, viewing the downloaded content, creating a schedule for requesting content, creating a content request, creating a user profile, choosing the type(s) of content the user wishes to download, creating a so-called wish list of desirable content, etc. The user profile may also be created automatically by the device based on the user's selections. The device can also be set up to automatically downloaded specific items on the wishlist (e.g. content of a particular type, or specific content by a particular author), or to notify the user when items on the wishlist are available for download. The user is also provided with the option of accessing the host site from the device or computer and using an interface on the host site to review and/or request content.

The user may interact with the mobile device 16 using the architecture of the mobile device 16 which may include, for example, a keyboard, a mouse, a touch screen, a trackball, and/or any other suitable type of user-operable input device(s). The output user interface may include, for example, a video display, a liquid crystal or other flat panel display, a speaker, and/or any other suitable type of output device for enabling a user to perceive outputted information.

FIGS. 4 and 5 each illustrate scenarios in which new content is available for download, according to embodiments of the present invention. The mobile device 16 can be configured such that a host-initiated notification informs the mobile device 16 that there is content available for download which may be desired by the user. The mobile unit 16 can then acknowledge to either start or postpone download. The mobile unit 16 can also inform the user that new content is available for download; or, in accordance with automatic operation based on for example the user's profile or the user's instructions, the mobile unit 16 can decide automatically to approve the content for delivery or deny the delivery request.

In Step S10 of FIG. 4, the host site 10 transmits a message to the mobile device 16 informing the device 16 that new content is available for download. In the scenario illustrated in FIG. 4, the device 16 approves the content for delivery in Step S11. The host site 10 then sends the content to the mobile device 16 in Step S12. In Step S13, acknowledgments are sent and logs are created in accordance with the present invention as explained herein.

In Step S20 of FIG. 5, the host site 10 transmits a message to the mobile device 16 informing the device 16 that new content is available for download. In the scenario illustrated in FIG. 5, the device 16 denies the delivery request in Step S21. The host site 10 then archives the content and/or queues the content for later delivery in Step S22.

FIG. 6 illustrates an embodiment of the present invention in which, in the event that the mobile device 16 is in an unreachable state (for example it is powered off or out of battery power), the Host notification will be timed out. In Step S30 the host site 10 transmits a notification to the mobile device 16 informing the device 16 that new content is available for download. If there is no response from the mobile device 16 after a predetermined period of time, the Host notification is timed out. Following the timeout, the host can decide to archive or queue the content for later delivery for when the designated mobile device resumes operation. The content can also be deleted. The host site can repeat Step S30 by re-transmitting the notification to the mobile device 16 in predetermined time intervals, in order to check whether the device 16 has resumed operation.

The possibility for utilizing a device for enriching a child's or other person's experience is great. In the case of children, it can be easy to foresee the use and application of such a device in a number of various settings. For example, in one example, the device can be used in the child's home play space, in his day care play space, or at the local supermarket cart where a parent could prop the phone/device into the cart or allow the child to hold it. The parent can then push ‘play’ and the phone/device pops open the latest childrens' book which had been automatically downloaded overnight. The childrens' book, adapted or created to fit in and be properly displayed on the data capable mobile device, can be delivered visually by way of a vivid screen display and audio via the speaker on the device. The virtual book can flip through page by page (with enhanced visual animation) automatically or manually, and can be narrated by a story-teller. As such, the child can watch, listen and learn the story while the parent is shopping. Effectively, the parent in this example can get on-demand children's content via a mobile phone/device. Other options are available for users of any age. It is of course to be understood that the examples described herein are illustrative only and in no way limit the present invention to the details described.

It should be noted that while the invention has been described above in the context of mobile phones/devices, the invention is not limited to such. For example, beepers/pagers, such as Blackberry pagers, that have visual and interactive capabilities along with a means of downloading the content (for example, over the air or attached to a computer) could be used as well; another example is a PDA (Personal Digital Assistant) such as a PalmPilot, SmartPHone, or PocketPC. Furthermore, this content can be used not only for recreational use, but can be used to provide instructional video/audio to an employee, such as, for example, an Airport Security Guard who can instantly learn what the latest suspicious shoes may look like by watching a downloaded training video.

As explained above, data is not limited to content specifically designed for children. Data/content can also be geared to parents for instructional purposes to suit the needs of the parents/teachers with regard to child rearing or health and safety issues. Additional, unrelated material suitable for the instruction or entertainment of the general public could also be delivered via the data capable mobile device of according to the present invention.

Additionally, there are numerous options available for charging users fees for use. The method of payment for the downloaded content can be by license agreement or subscription. Users can pay per item of content downloaded or per block of items of content downloaded, for example. Users can also be charged a daily, montly, or yearly fee, for example, thus giving that user unlimited access to downloads of content, or access limited by certain restrictions depending on the plan the user selects.

Furthermore, the user can determine which type or genre of content he or she wishes to download, or which type or genre he or she wishes to receive notifications of. The user can choose to automatically download the latest content periodically (e.g. hourly, daily, weekly, monthly, etc.), or automatically as new content in a particular genre is available, for example. The user can choose to automatically download and/or display content at a certain time of day.

The user can program a schedule as well, and program how often content is to be delivered, as well as a requested type or genre. The mobile device can be programmed such that it searches the list of available content for specific criteria, such as a specific topic or author. The mobile device can be programmed such that it specifically notifies the host of desirable content, which information the host can use to notify the host administrator that such content is desired, or search for such content itself.

Data can be uploaded to the host site by a site administrator or by authorized content providers. Various data compression/encoding, decompression/decoding, and storage techniques are well known in the art and can be used to implement this invention.

In one example a controller controls the operations of the host site, including storage of the content on the host site, cataloging the content, and delivering the content to the mobile device. A controller in the mobile device controls the scheduling, media processing/playback, requesting of content, and user interaction.

Low power techniques are also used to prolong the on-time of the device. For example, audio options can be turned off or the volume lowered. As an example, if content is being read by a virtual narrator according to the features of the present invention, that audio can be turned off or down.

A storage medium for storing program code of software for executing the functions of the present invention can be provided in a system or apparatus. A computer, such as a CPU or MPU, in the system or apparatus can read and execute the program code stored in the storage medium. In this way, the functions of the present invention can be implemented. The storage medium for supplying the program code can be a hard disk, a floppy disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, a ROM, and others. The functions of the present invention can also be realized by executing some or all of the processing by an operating system which operates on a computer on the basis of the instructions of the program code.

While the invention has been particularly shown and described with respect to preferred embodiments thereof, it will be understood by those skilled in the art that changes in form and details may be made therein without departing from the scope and spirit of the invention.
